研究不同浓度的壳聚糖浸种对花生产量及其源积累、库扩充和有机物分配的影响。结果表明,①壳聚糖提高了花生的生物产量和经济产量,分别比空白处理增加18%~53%、9%~63%；②促进花生根、茎、叶前期快速生长、中后期持续稳定生长；③壳聚糖增加了花生单株总果数、饱果数和总果重等产量性状；④2.5 mg /mL 壳聚糖浸种处理的经济系数显著低于空白处理,5.0~12.5 mg /mL 壳聚糖处理与空白处理间均无显著差异；⑤壳聚糖处理后产量与源、库性状间相关性最大,与流相关性最小。其中7.5 mg /mL 处理的产量、营养生长和生殖生长最适,与清水处理间的差异均达显著水平。

The experiment was conducted to study the effect of seed soaking with chitosan of dif-ferent concentrations on the yield and the source accumulation, sink expansion and organic matter dis-tribution of peanut.The results showed that: ① Chitosan enhanced peanut's biomass yield and eco-nomic yield by 18% ~ 53%, 9% ~ 63% respectively compared with the control treatment.② Pro-moted roots, stems and leaves to grow faster in early period and grow sustainably and stably in the middle and late period.③ Chitosan increased peanut's number of all pods, plump pods and total pod weight of per plant; ④ Economic coefficients of seed soaked with 2.5 mg /mL chitosan was signifi-cantly lower than control treatment, while those with 5.0 ~ 12.5mg /mL chitosan had no significant difference comparing with it.⑤Yield relevance with source and sink under treatment of chitosan were the highest, while that of flow was the least.The treatment of 7.5mg /mL was the optimum concen-tration, and the peanut yields, nutritional growth and reproductive growth were all significantly dif-ferent with control treatment.
